Hardware :: External Hdd Stop Working - How To Repair
Aug 31, 2009
my external hardrive has decided to stop working! It just wont appear on the desktop, disk utility doesnt see it nor does system profiler register anyhting being there. Its a Taurus Raid II external hardrive with two Seagate Barracuda 7200 RPM 500gig harddrives in it.
I've tried all of the ports it has on the back as well as plugging it into a different computer made sure that the power souce is legit. Where am i going wrong?
2007 iMac Snow LeopardAny idea why my external speakers would stop working? This happened after I unplugged speakers from outputand plugged in headphones. After done, when I pluggedspeakers back in it stopped working. Headphones no longer work either. Internal speakers still do, though.I went into preferences and sounds. The external speakers are no longer showing up. Built in output is the only option available. I unplugged everything and turned everything off. Plugged them back in and turned the mac back on. Nothing.
While watching today apple keynote. At the and i realized that my retina display is totally black. Mirror display through hdmi is ok, apple logo on back side of disply is not lighting.
My MBP has this issue every once in a while where I have to hold the power button and force shut down. Randomly the volume keys/brightness etc. stop working and i can't open apps or shut it down normally. Everything still works though (can still function in open applications) Anyone know what the problem is? It fixes when I force reset.
I am using OS X 10.3. The apple menu doesn't work (for the past few months). When I click on it it's highlighted but doesn't pull down. I can not quit applications even if I use keyboard shortcuts (I have to force quit).
I tried starting with "safe boot" and I ran "Verify & repair disk permissions" but it didn't fix it. Any ideas?
i'm having alot of problems since i got this mac pro and the first problem is fan sound:

second problem which is now the ram slot 2 (The Lower) isn't working properly, every time i run the computer it gives me that gray screen and tells me to keep holding the power button, but when i removed the ram slot 2 it works properly with only the upper slot ram, and to check the problem source, i switched between the upper and lower, and it worked properly but with out adding the upper slot in the lower space, so i knew that the problem now is 100% from the logic board.... right or is there an another way?

I am unable to use my OS X disks to boot from. The DVD drive tries to read and then ejects them. Blank DVD's can be formatted and written. The text below is what repair disk reports: ACL found but not expected on "Applications/Utilities". Permissions repair complete
I got a mac mini back in february, i think it has a 1 year warranty on it but the thing is i bought the keyboard seperately so im afraid i may need a new one if i cant fix this. Yesterday my right and down arrow keys stopped working. I checked under them and they look perfectly fine, they just dont respond.
I am trying to set up my external HD with my Airport extreme and make it as my time machine so it will back up without me having to connect the HD every time. I tried this and the HD does not appear so i can select it and choose it for the Time machine Drive of choice. What do i do. I have seen others can do this but i do not know why i am unable.
I have a late 2009 Mac mini that I bought in March. 2 weeks ago I tried to use an apple remote with it and it would not work. Apple change the IR board on the mini. After 10 days I picked my mini up from the apple store and I noticed 4 marks from when they opened the mini. Ripped aluminum gouge marks on the bottom of the case, the back of the case by USB port does not line up anymore. I brought it to there attention but did not make a big stink and left. I have open a few mini's before (not this one)and know how it is easy to mess up.
When I got home I tried to use my bluetooth devices and they would not work, I tried the magic mouse, track pad, KB. I called apple to trouble shoot and they said I have to bring it back in for repair after 20 minutes of trouble shooting.
Recently I had a issue with my macbook pro so I had it repaired at the Apple Store(problem with the display). They replaced the logicboard(2nd time in 4 months) and the battery. Now after taking it hope and plugging in my external speakers into the headphone jack I get this weird thump sound. It happens twice and I'll watch the audio strength at the top right. Each time it goes from like it's working to a gray color as if it's not or locked. If I try to play something like music with the jack in my entire screen freezes and I have to restart my computer entirely for it to work. Btw there is no red light in the headphone jack. The last time I had the logic board replaced it was a sound problem.
Info: MacBook Pro, Mac OS X (10.7.4), Just replaced the logicboard
The keyboard and trackpad on my macbook cut out about six months ago and since then I've been using an external keyboard & mouse. I've only just got round to taking my computer in to be looked at at the genius bar, and what I've heard back is that the connections between the logic board and keyboard top section are damaged, and I've got a quote for <$400 for both to be replaced, which is apparently the only solution. The bulk of the cost is the new logic board, and seeing as it's only a connection rather than the processor itself that is damaged, I'm wondering whether it would be possible to have the logic board component repaired or replaced rather than replacing the entire thing.
Ive recently had to repair my startup disc volume/reinstall Tiger and now my iPod doesnt store songs after I sync it. All of my music is in iTunes and everything else seems to be working however once I disconnect my iPod NOTHING is there.
Ive been looking through all the previous discussions but cant seem to fix this on my own. And Im not even sure if I should be posting this question on here or in another forum...because Ive also noticed that there are no pictures in iPhoto .when I did the repair...it asked me if I wanted to save a copy of the previous system which I did.
After some various installations and file copy from/to external hard drives i ran the repair permissions on the bootup hard drive.
There was a listing about a mile long. Whoa, that does not look good to me.
So, i ran the persmissions repair again: another mile long listing: yikes.
Yep, ran another permissions repair and same thing.
How many times do you have to run permissions until it just show a few permissions that had to be corrected ? Or is this a sign that the system is in trouble.
This was an external FW drive with Leopard run by iMac 3.06GHz.
I just took the hard drive out of my old ibook g4 and put it in a case to use an external.
But for some reason it won't show up? I looked in disk utility and its there but i cant mount it or repair it or anything. tried it on my wife's mack book same deal. i need the data on it.
Last night I noticed that the time machine icon on the menu bar had a stop sign or something and when i clicked back up now it says it can not back up. I verified the volume and recommends a repair but it says it can not repair.
So so annoyed right now. Today my 12" G4 powerbook started to become slow, lots of spinning wheel, delayed menus etc. I checked file permissions, rebooted and it just kept on getting slower. Eventually it wouldn't get past the white apple screen.
I booted off the Tiger DVD and ran disk utility to fix and repair permissions again. It wouldn't let me repair the disk as I kept getting this error:
'Repair volume failed with error could not unmount disk'
I had to reboot again, and eventually my hard disk no longer appears in Disk Utility. I tried to boot into safe mode and get this:
'"I0ATAController device blocking bus I0ATAController device blocking bus I0ATAController device blocking bus I0ATAController device blocking bus I0ATAController device blocking bus"
So now I pretty much can't do anything with it. Failed Hard Drive?
Last night I encountered a problem with my seagate FreeAgent external HD/D. I right-clicked on the desktop icon to eject it as per usual and once the icon had vanished I pulled out the USB cable. However, I then got a message saying that I didn't eject the device properly and might have lost data, etc. When I plugged the external drive in this morning I found that it wouldn't mount. I am in a state of panic at the moment because it is almost 150gb of data that I really did not want to lose! I read in one of the previous threads that this is a common problem amongst macs but I wasn't able to discern if this was a permanent error and if it means my drive is shafted. I ran disk utility and this is what it came up with:
Verifying volume "disk1s1" Checking HFS Plus volume. Invalid node structure Invalid B-tree node size Invalid node structure Invalid B-tree node size The volume needs to be repaired. Error: The underlying task reported failure on exit 1 HFS volume checked Volume needs repair
I tried to repair it using disk utility but it wasn't able to do it. I am now using the demo of Data Rescue II to do a thorough scan which will take several hours but I'm wondering what options I have. Are there any other mac tools I can use? I am a total newbie when it comes to macs having only made the transition from PC to Mac several months ago and I don't know what tools I can utilize to fix this problem, if it even can be fixed.
I never know when my keyboard on my iMac wil just stop. I have to unplug if from the USB and re-plug it to start working again. I've had the same setup for a couple of years. Started doing this about 1 month ago.
I'm having a series of problems. First some intermittent audio problems with Garageband, then, then some external drives won't mount, and now I can't sync to my disk from the iMac. I've run Disk Utitilies a few times and when I do Verify Disk Permissions, it finds a list of things to fix, I then hit Repair Disk Permissions and it fixes them, and then hit Verify Disk, and it say the disk appears ok. When I do Verify Disk Permissions again though, it finds another long list of things to fix. Is this serious? What should my next step be? Should I reinstall the entire system?
All of my music is on an external hard drive connected via USB. It is now showing that instead of having 80+gb of data there is zero and now a file that says USBC and some other characters. I tried running disk utility and it said "filesystem verify or repair failed". Music folders and files disappeared from external hard drive now showing USBc file.
Every now and then while I'm on the laptop for a while my keys stop working out of no where. I hit the keys and nothing comes up? So I have to shut it down or restart then it works again. Is there something wrong with it or is there randomly something I'm doing?
I recently have been running into problems with my Macbook Pro in that an hour or two after startup, the hot corners no longer work and command tab no longer works. That is when I try to use them nothing happens at all. The keyboard still functions normally other than that. Also, if I then try to shutdown the system appears to begin the shutdown in that my desktop icons disappear, but then the machine just sits there and will never shutdown. I am then forced to hold the power key down to force a hard shutdown. Then once I do a startup, I have my hot corners back and command tab works. Until it sits for a while and then I start the cycle over.
It happens randomly. After awhile the keyboard and trackpad stop working entirely. I have to use my might mouse to reset my MBP then it they work fine again.
I live in Canada where there is no apple store. My trackpad has stopped working, and Apple Canada support told me to drive the the states North Dakota to get it fixed. I was wondering cant they just send me a mailer and I mail it in?
Periodically, all links on a page (any page including Apple) will stop working. Quitting Safari and the restarting works to clear the problem until the next time. The links fail to work with either the mouse or the trackpad.
Info: iMac, Mac OS X (10.7.2), Pentax K7, K10D, K20D
Had issues with videos suddenly not working on Safari, but working on Firefox. With my limited tech skills, finally figured it out & went to Adobe and downloaded a new version of Flash and that seemed to fix it. Dont really understand why it stopped working overnight when I hadnt manually changed anything. (I always hear iphones dont play flash video so does that mean all these websites I was trying to access wouldnt work on an ios device? That seems crazy to me...It was a wide range of websites and videos)...
